Title: Wiper
Inventor: TAKAHASHI TAKERU
IPC: B60S1/38
Filed: 1992-12-16
Abstract: PURPOSE:To suppress generation of a vibration or a noise when the attaching amount of the water and the like is small, while maintaining the wiping capacity of the blade rubber assembled to a wiper blade to the water and the like on a glass surface. CONSTITUTION:By burying a staple in a blade rubber 7 of the backward moving side half 9 of a wiper blade, the water is wiped by a pure rubber at the forward moving side half 8, in the condition having a much amount of water on a glass surface 1. And in the backward side where the water amount is reduced, the surface of the glass 1 is wiped by the rubber mixing the staple to reduce the friction force with the glass 1 surface, so as to move smoothly, and generation of a vibration and a noise is reduced.

Title: Method and device for development
Inventor: YAMAGUCHI CHISEKI
IPC: G03G13/08
Filed: 1989-12-25
Abstract: PURPOSE:To provide a novel development method by opposing the thin film of a developer formed on a developer carrier having a photoconductive material layer on a transparent electrode to an electrostatic latent image carrier and irradiating the thin film with developing light from the transparent electrode side. CONSTITUTION:The transparent electrode 1b and the photoconductive material layer 1c are laminated on a transparent substrate 1a to form the developer carrier 1, and the electrode 1b is grounded. The developer T having a charge of the same polarity as that of the charged layer 1c is deposited on the layer 1c, and the layer 1c is charged by the charge of the developer T. The electrostatic latent image carrier 10 having an electrostatic latent image is approached to the carrier 1 with the developer T deposited on the layer 1c, and the developer T is transferred to the picture equivalent part by electrostatic attraction. The developer is irradiated with developing light from the back side of the substrate 1a. A carrier is generated in the layer 1c by photoelectric transfer, hence the adhesion of the developer T to the layer 1c is weakened since the charge is neutralized, and the developer is transferred to the carrier 10. The developer T remaining on the carrier 1 after development is removed by a blade 4.

Title: Voltage application circuit
Inventor: ORITO MASAHIRO
IPC: H03K19/094
Filed: 1991-12-19
Abstract: PURPOSE:To obtain the voltage application circuit in which a semiconductor integrated circuit receiving a back bias voltage causes no malfuction when a back bias voltage generating circuit is turned off. CONSTITUTION:A voltage from a power supply voltage Vcc is fed to one input of an EXOR circuit 3 via delay inverters 4, 5, 6, 7 and the voltage is directly inputted to the other input. When the power supply voltage Vcc changes from an H level to an L level, the EXOR circuit 3 outputs an H level only for a period corresponding to a delay time in the inverters 4, 5, 6, 7 and an NMOS TR 10 is turned on in response to the H level. A back bias voltage VBB reaches a ground potential GND by turning on the NMOS TR 10. As a result, when the power supply voltage Vcc is interrupted, since the back bias voltage VBB reaches quickly the ground potential GND, malfunction of the semiconductor integrated circuit receiving the back bias voltage VBB is not caused.
